I MPROVE MENT IN MOTORS FOR SEWING-MACHINES.

Specification-forming part of Letters Patent N o. i90,664. dated May 17; applicat o l December 11, 1876.

. thereon, which form a part of this specification.

Figure 1 shows the wheel. Fig. 2 shows side view of wheel-box andflexible pipe leading to sewing-machine. Fig. 13 shows the head It andpiece of the coiled wire.

The purpose of my invention is to provide a new and improved device fordriving a sewing-machine by water or steam. My device contemplates aconnection with a faucet where a small pressure exists sufficient forthe purpose of driving the machine, or a connection with any'waterpressure or power which may be convenient or at hand in a house ordwelling. I

In the drawings, a shows the pipe through which the water is led intothe box b and on to the wheel. Within the box is any convenient form ofovershot water-wheel revolving on the shaft 0, having bearings in thesides of the box. The box is provided with a base, 0, so that it may bescrewed down to a floor or table, or other support, and thus secured inposition and held firmly while the wheel within is revolving.

f is a flexible tube or pipe, which is secured to a sleeve whichsurrounds one end of the wheel-shaft where it projects through the sideof the box b. Within this flexible tube is a coiled wire, g'. This wireis rigidly connected with the end of the wheel-shaft, which is inclosedwithin. the flexible tube before referred to, and revolves with saidshaft. On the outer end of this coiled wire is fixed a head, it, whichis the means I provide for connecting the coiled wire to the hubs of thewheel of the sewing-machine. To thisend I provide the head withprojecting parts i j to pass between the spokes of the wheel of thesewing-machine, and tightly clasp the.hub. In addition to this I providethe bent piece I, which hasan eye, m, in the end of the same. This eyeis to receive a bolt or screw, by which the head It is screwed to thewheel.

The partl is made of length sufficient to extend to the place on thewheel-spoke where the treadle-levcr is screwed to the wheel.

When using my device the treadle-lever is unfastened from the wheel, andthe piece l is screwed to the wheel in its plae. When this device isscrewed to the wheel the revolution of the wire 9 is communicated to theshaft of the machine, and it is thus driven by the water flowing uponthe wheel. 1?. is a brake working through the outer end of the tube f,in order to stop the revolution of the wire when desired.

A proper metal ring may be fitted to the end of the flexible tube forthe screw to work in. The end of the tube next to the machine should beso secured as to prevent its revolution with the wire within it. To thisend I attach a hook or holder to the back braces of the machine, andsecure the tube therein. by a set-screw, but not exerting pressureenough with the screw to stop the revolution of the coil-shaft.

My invention is not limited to the use of the water-wheel.

In cases when shafting is at hand my tube and coiled wire can be used byhaving two heads like h, one at each end of the wire, one to fasten toan end of the shafting, and the other to the wheel of thesewing-machine, as set forth.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of the flexible tube f, having within it the' coiledwire g, with the head h, having the parts ij k, and bent piece l, andbrake n, as herein set forth, and for the purposes described.

2. The combination of the box I), the wheel, the pipe (1, flexibletubef, coiled wire g, head h, with parts i, j, and Z, to be attached toa sewing-machine, as herein set forth.

In testimony that I claim the foregoing as my own, I affix my signaturein presence of two witnesses.

ALBERT D. BLACK.
